BUMPIG-POST FOR: RAILROADS.

To all whom t may concern.' n

Be it known that I, EDWARD C. HOLMES, a citizen of the United States, and a resident of the city of Norwood, in the county of tively withstand the shock of heavy blows.

rIhe invention consists of thatv certain novel'construction andarrangement of part-s to be hereinafter particularly pointed out and claimed whereby the body of the post may be constructed of concrete adapted to withstand great crushing strains and in which the force of the blow delivered longitudinally to the receiving head may be translated largely in a downward or vertical blow by reason of the pivotal construction of the l pivot pins for the rock arms. The bumping post proper is a solid and y larger springs 5.

In the drawings, `Figure 1 is a side eleva-` tion of my improved construction with part of the receiving head in section. Fig. 2 is a top plan view of the same. Fig. 3 is a front elevation. Fig. lis a detailed transverse section of the track support in front of the bumper attachment. Fig. 5 is a perspective view of the supporting plate for the receiving head. Fig. 6 is a perspective view of the rail supporting plate. Fig 7 is a side and end elevation of one of the substantial standard 1, preferably constructed of concrete and preferably in theV Bolted with bolts 7, 7, or otherwiseper- Specification of Letterselatent.

manently and effectively secured ontop of the truncated upper end of the standard 1,

1s a bearing plate 8, with vertical side flanges 9, 9, and mounted to rock between these side flanges is the substantial metal casting 10, forming the receiving head for the bumper. vThis head is provided with an angular or curved rocking surface 11 and with a socket 12 in which is seated the striking plate 13, with the socket portion preferably cylindrical in shape and formed with steps or shoulders 111 on its inner end. Interposed between the striking plate and the basel of the socket are a series of coiled springs 15, 16 and 17, one within the other, seated' on the stepped portionof the striking plate, with the larger and heavier springs on the outside.

Securely bolted to the sides of the head -10 by the bolts 18 are the rocker arms 19,

19. lfhese` arms extend downwardly and flare outwardly to the width of the track rails20 in front of the bumping post where they are pivotally `mounted by the substantial pivot pins 21 on the upwardly extending lugs 22, 22 of the securing plates 23. These plates have depending flanges 24 to engage the web of the vrail where they are securely bolted by the. bolts25. As` these bolts are subjected to great strain when the bumper post is struck, they are provided with the ears 26 to receive the ends of the U-bolts or straps 27, vwhich pass down on each side ofthe rail alongside of the sleeper 28` and around anI-beam 29 underneath the sleeper. These Ibeams extend some distance along underneath `and parallel to the track, and the track rails are further strapped to these I-beams by the U-bolts or straps 30, which engage the rail flanged plates 31, which are slipped over the rail from the end to engage the flange of each side'. In this way the receiving head of the bumper is securely coupled to the track construction.

Vhen the bumper post is struck by the rolling stock, the striking plate 13 receives the blow yieldingly by reason of the coiled springs, and the receiving head 10 is rocked to direct the force of the blow downwardly upon the concrete standard. The rocker arms 19 also rock on their pivots 21 to properly allow for this change of direction of the blow.

Having thus described my invention, what whereby the force of a horizontal strikingblow may be converted into a blow at right angles thereto upon the concrete standard. 2. In a device of the character specified,

a concrete standard, with a yielding vertical support therefor, a receiving' head slidingly mounted thereon, rocker arms secured to the receiving' head, with pivotal connec tions for the rocker arms with the track structure whereby the force of a horizontal striking blow may be converted into a blow at right angles thereto upon the concrete standard.

3. In a device of the character specified, a concrete standard, with a'yielding vertical support therefor, a receiving head slidinglj,y mounted thereon, rocker arms secured to the receivinghead, with pivotal connections Jfor the rocker arms with the track structure, the receiving' head provided with awhorizontal socket and al striking plate mounted in the socket in the receiving head, with springs to serve as a yielding cushion.

4l. In a device of the character specified', a vertical standard, with a bearing` plate on top thereof, the plate provided with side flanges, a receiving head mounted to slide and to rock between said flanges, and rocker arms secured to the receiving head and pivotal connections with the track structure.

5. In a device of the character specified,

Copies of this patent may he obtained for vecents each, by addressing the Commissioner of Patents, I

a vertical standard, with' yielding` cushion for the standard, and a bearing' plate on top of the standard, thefplate provided with side flanges, a receiving head mounted to y slide and to rock between said flanges, and rocker armssecured to the receiving head and pivotal connections with the track structure.

`6. In a device of the character specified,

a vertical Standard, a receivimq,V head slid ingly mounted thereon, a track structure comprising' rails and sleepers, with I- beanis underneath the sleepers'parallel with the track rails, securing plates bolted to the track rails, and U-straps to secure the securing plates `to the I-beams, with rocker` arms secured at one end to the receiving head and pivotal connection for said arms f at the other end to the securing' plates.

A7. Ina device of the character speciiied,

a standard, a receiving ,heady slidingly G0 mounted thereon, rocker arms secured to the receiving head, with pivotal connections for oy the rocker arms :with the track structure, the receiving' head provided with avhorizontal socket, and a striking' plate mounted in the socket in the receiving' head, the strikingV plate provided with a stepped portion in the rear, and a series of coiled springs graded in size seated between the stepped portion and the haselof the socket to serve as a yielding cushion with the smaller springs inside thelarpger.
